Anti-Smooth Muscle Antibodies (ASMA)

Indirect immunofluorescence test for the qualitative determination of antibodies against smooth muscle (ASMA) in serum or plasma.

Tissue sections from rat stomach are used for the detection of anti-smooth muscle antibodies (ASMA) in serum or plasma. ASMA bind to the corresponding antigens in the muscle layers of the blood vessels and the interglandular fibrils in the rat stomach. Anti-smooth muscle antibodies are the standard diagnostic markers for autoimmune hepatitis. Anti-actin antibodies, a subgroup of smooth muscle antibodies, are found in the sera of 52-85 % of patients with active chronic autoimmune hepatitis and 22 % of patients with primary biliary cirrhosis. Their presence in other autoimmune diseases, like cholangyopathy, reflects overlapping features of those diseases.
